The 2025 Harley-Davidson® Low Rider® ST combines a blend of traditional styling cues with a comprehensive set of modern mechanical and electronic features designed for performance and control. The motorcycle emphasizes functionality through a high-output powertrain, advanced suspension components, integrated rider technologies, and enhanced safety systems.
Engine and Powertrain Specifications
The 2025 Harley-Davidson® Low Rider® ST uses the Milwaukee-Eight® 117 High Output engine, a V-twin powerplant tuned for improved mid- and top-end performance. This engine produces 114 horsepower and 128 foot-pounds of torque, generating strong acceleration and sustained power delivery across a broad rev range. The engine redline has been increased from 5,600 to 5,900 revolutions per minute, which allows for extended throttle application during aggressive riding.
Air intake is managed by the Heavy Breather intake system, which is forward-facing to maximize airflow and optimize charging efficiency. This design contributes to improved torque output and engine responsiveness. The exhaust system is a redesigned two-into-one layout that provides a symmetrical appearance for the saddlebags and supports exhaust flow optimization.
Fuel efficiency is rated at approximately 47 miles per gallon, reflecting a balance between performance output and operational economy.
Frame and Aerodynamics
The motorcycle features a frame-mounted fairing inspired by the FXRT model. This fairing is constructed using computational fluid dynamics principles to optimize aerodynamics and reduce rider fatigue caused by wind resistance during longer rides. The fairing houses an LED headlight, which improves forward visibility compared to conventional lighting systems. Complementary LED turn signals and a redesigned taillight enhance visibility to other drivers, providing consistent signaling clarity.
Suspension and Chassis Dynamics
The chassis setup of the 2025 Harley-Davidson® Low Rider® ST focuses on delivering handling precision and rider confidence. The front suspension includes a 43-millimeter inverted fork, which increases front-end rigidity and responsiveness.
The rear suspension utilizes a tall monoshock system that increases ground clearance during lean, allowing for greater cornering angles without sacrificing ride comfort. This setup supports a sporty riding style while maintaining stability over various road surfaces.
Braking is managed by dual front discs. These discs provide substantial stopping power and are paired with a braking system that integrates with the bike’s electronic safety features. The braking system is complemented by Michelin® Scorcher® 31 tires, which offer a balance of grip, handling, and durability suited to the motorcycle’s sport-touring purpose.
Rider Interface and Controls
The instrument cluster consists of a traditional analog speedometer paired with a four-inch multi-function digital display. This digital display presents critical ride information such as selected ride mode, tire pressure monitoring system (TPMS) status, gear position indicator, and other diagnostics.
Hand controls have been redesigned to improve rider interaction. The controls include ride mode selection buttons, an adjustable brake lever, and a repositioned flash-to-pass switch located near the left forefinger for ease of use without distraction.
Connectivity features include a USB-C charging port integrated within the console area. This port supports device charging, allowing riders to maintain power to smartphones or GPS devices during extended trips. Bluetooth® headset integration enables hands-free communication and audio functions.
Rider Safety Systems
The 2025 Harley-Davidson® Low Rider® ST incorporates a comprehensive suite of Rider Safety Enhancements to assist in various riding conditions. These systems employ sensors and control algorithms to modulate braking, throttle, and traction control based on real-time data from the motorcycle’s lean angle, acceleration, and wheel speeds.
The Anti-lock Brake System (ABS) prevents wheel lockup during emergency braking situations, helping maintain steering control. This system is adapted into a Cornering Enhanced ABS (C-ABS) version, which adjusts brake pressure dynamically according to lean angle to avoid loss of grip during turns.
The Traction Control System (TCS) reduces rear-wheel spin under acceleration, maintaining stability during quick throttle application on various surfaces. This system is extended to a Cornering Enhanced Traction Control System (C-TCS), which modulates traction based on both acceleration and lean angle.
The Drag-Torque Slip Control System (DSCS) manages rear-wheel slip caused by rapid downshifting or abrupt throttle closure, conditions that can induce rear-wheel lock or slide, especially on slippery or uneven road surfaces. The cornering variant (C-DSCS) adjusts these controls while the motorcycle is leaned over in a turn, providing enhanced safety during aggressive cornering or sudden deceleration.
Additionally, the Tire Pressure Monitoring System (TPMS) continuously monitors air pressure levels in the tires and alerts the rider through the digital display if pressures deviate from optimal levels.
Storage and Customization Features
The 2025 Harley-Davidson® Low Rider® ST is equipped with two lockable saddlebags providing a combined storage volume of approximately two cubic feet. These storage compartments are designed to integrate with the motorcycle’s streamlined profile and fairing system.
The styling integrates a retro heritage aesthetic with a modern finish. The fuel tank displays heritage-inspired graphics, and premium paint options are available, including Billiard Gray, Vivid Black, Brilliant Red, Iron Horse Metallic, and Midnight Firestorm for the Black trim, as well as Blue Burst on the Chrome trim.
Integrated Ride Modes and Technology
The 2025 Harley-Davidson® Low Rider® ST includes three selectable ride modes that adjust engine response, throttle mapping, and traction control parameters. These modes allow riders to tailor the motorcycle’s behavior to road conditions or personal preference. The modes are accessible through the handlebar controls and displayed on the instrument panel for immediate feedback.
The integration of these ride modes with the safety systems ensures a coordinated approach to stability, traction, and braking control. This integration improves handling confidence across varying riding environments, from tight cornering to highway cruising.
